Say I'm on computer A and I use SSH to get a console on computer B. Then through this SSH console I copy files from computer B to computer C.
ME (Computer A) | | (ssh to) Computer B ----------> Computer C (copy files to)
What network traffic comes over the wire to me and my console and what traffic only moves between computer B and computer C? Is my assumption that the copied files' data only moves between B & C and not A & B?
